Description

Technical Field

[0001] This utility model relates to the technical field of internal wall cleaning devices, and more particularly to a boiler flue cleaning device for cigarette factories. Background Technology

[0002] Boilers are used in the cigarette production process for air conditioning and heating. The heat from the boilers also generates steam for the vacuum rehumidification process in the cigarette making process.

[0003] During boiler operation, various types of scale easily accumulate on the inner wall of the flue. This scale not only affects the boiler's thermal efficiency but can also lead to problems such as flue blockage and corrosion, seriously threatening the safe operation of the boiler. Therefore, regular cleaning of the boiler flue is a necessary step in maintaining the normal operation of the boiler.

[0004] Traditional boiler flue cleaning methods mostly involve manual cleaning or simple mechanical cleaning tools, but these methods have many shortcomings. Manual cleaning is labor-intensive, inefficient, and poses a potential threat to the health of workers; while simple mechanical cleaning tools are often ineffective and fail to thoroughly remove the scale buildup on the inner walls of the flue.

[0005] To address these issues, some cigarette factory boiler flue cleaning devices have emerged on the market. These devices typically use a rotating rod to drive a brush head, mechanically removing scale buildup from the flue's inner wall. This method is simplistic, and the removed scale can easily remain inside the boiler flue, causing secondary pollution. Furthermore, during the cleaning process, the brush head, which can trap chunks of scale, can easily scratch the boiler flue, causing further damage. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a cigarette factory boiler flue cleaning device, which solves the technical problems of the prior art where the dirt cleaned by the cigarette factory boiler flue cleaning device is easy to remain in the boiler flue and cause secondary pollution, and the brush head mixed with blocky dirt is easy to scratch the boiler flue when rotating, causing secondary damage.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0010] In a first aspect, this utility model provides a boiler flue cleaning device for a cigarette factory, including a rotating rod, a brush head, and an outer tube. The brush head is fixedly connected to one end of the rotating rod, and the outer tube is sleeved on the outside of the rotating rod to form a medium channel between the two. The end of the medium channel near the brush head is the front outlet, which is located behind the brush head. The rotating rod, brush head, and outer tube can all be inserted into the boiler flue. When the rotating rod drives the brush head to rotate along its own axis in the boiler flue, the front outlet can output a positive pressure medium.

[0011] In one technical solution of this utility model, a power assembly is also included. The power assembly includes a rotation drive and a positive pressure medium generating device. The drive end of the rotation drive is fixedly connected to the rotation rod, and the output end of the positive pressure medium generating device is connected to the medium channel. The power assembly also includes a housing, and the rotation drive and the positive pressure medium generating device are both supported inside the housing.

[0012] In one technical solution of this utility model, the positive pressure medium generating device includes an air pump.

[0013] In one technical solution of this utility model, the positive pressure medium generating device includes a water pump and a liquid storage tank. The liquid storage tank is connected to the inlet end of the water pump so that the water pump can output cleaning liquid to the medium channel.

[0014] In one technical solution of this utility model, a plug is also included. The plug is sleeved on the outer periphery of the outer tube and can seal the gap between the outer tube and the boiler flue when the brush head is inserted into the boiler flue.

[0015] In one technical solution of this utility model, the plug is axially slidably connected to the outer tube, and the plug can be supported in the boiler flue in a tensioned manner.

[0016] In one technical solution of this utility model, the plug is fixedly connected to the outer tube, and the plug is axially slidably connected to the boiler flue.

[0017] The outer periphery of the plug forms a scraping ring that abuts against the inner wall of the boiler flue, so as to scrape off impurities on the boiler flue as the plug slides axially with the outer tube.

[0018] In one technical solution of this utility model, a mesh bag and a retaining ring are also included. The mesh bag is detachably connected to the front end of the boiler flue via the retaining ring, and a storage cavity communicating with the boiler flue is formed inside the mesh bag. The retaining ring is detachably connected to the opening of the mesh bag and can be inserted into the boiler flue to press the opening of the mesh bag between the retaining ring and the boiler flue.

[0019] In one technical solution of this utility model, a camera is also included. The camera is fixedly connected to the front end of the outer tube and is suitable for taking pictures of the inner wall of the boiler flue after the outer tube is inserted into the boiler flue.

[0020] In one technical solution of this utility model, the rotating rod is a flexible rod, the outer tube is a flexible sleeve, and both the flexible rod and the flexible sleeve are capable of bearing axial force.

[0021] (III) Beneficial Effects

[0022] The beneficial effects of this invention are as follows: When the cigarette factory boiler flue cleaning device is inserted into the boiler flue, the rotating rod drives the brush head to rotate along its own axis, mechanically cleaning the scale buildup on the inner wall of the flue. Simultaneously, a positive pressure medium is sprayed out from the front outlet through the medium channel, assisting the brush head in cleaning and also reducing the temperature of the brush head and the boiler flue during cleaning. Through the combination of mechanical cleaning and medium-assisted cleaning, this device can more effectively remove scale buildup from the boiler flue, thereby improving the operating efficiency and safety of the cleaned boiler.

[0023] Because the front outlet is located at the rear of the brush head, the output positive pressure medium can directly impact the brush head, thereby efficiently removing the blocky scale trapped on the brush head and avoiding the problem of scratching the inner wall of the boiler.

[0024] Meanwhile, because the medium flows through the medium channel while the rotating rod rotates, it can remove the heat generated by the friction between the rotating rod and the outer tube, thus increasing the service life of the rotating rod and the outer tube, and consequently extending the overall service life of the cigarette factory boiler flue cleaning device. When the positive pressure medium is liquid, it can also be used to lubricate the rotating rod and the outer tube, reducing the rotational resistance of the rotating rod and thus reducing the energy consumption of the cleaning device, further extending its service life.

[0025] In summary, the cigarette factory boiler flue cleaning device of this utility model fully combines the advantages of mechanical cleaning and media-assisted cleaning, improving the cleaning efficiency, cleaning effect and service life of the boiler flue. Attached Figure Description

[0041] To better explain and facilitate understanding of this utility model, the following description is provided in conjunction with the appendix. Figures 1-6 This invention will be described in detail through specific embodiments. The term "before" as used herein refers to... Figure 1 The right side of the middle, the back is Figure 1 Left of the middle.

[0042] Example 1:

[0043] Reference Figures 1-6 This utility model provides a boiler flue cleaning device for a cigarette factory, including a rotating rod 1, a brush head 2, and an outer tube 3. The brush head 2 is fixedly connected to one end of the rotating rod 1, and the outer tube 3 is sleeved on the outside of the rotating rod 1 to form a medium channel A between the two. The end of the medium channel A near the brush head 2 is the front outlet B, which is located behind the brush head 2. The rotating rod 1, brush head 2, and outer tube 3 can all be inserted into the boiler flue 100. When the rotating rod 1 drives the brush head 2 to rotate along its own axis within the boiler flue 100, the front outlet B can output a positive pressure medium.

[0044] The rotating rod 1 transmits power to the brush head 2, enabling it to rotate. The rotating rod 1 can be driven by an external power source, such as an electric motor, ensuring continuous and stable rotation within the boiler flue 100. The brush head 2 is fixedly connected to one end of the rotating rod 1 and is the component that directly contacts the inner wall of the boiler flue 100. The material and design of the brush head 2 must be selected based on the material and characteristics of the scale buildup on the inner wall of the flue to ensure effective removal of scale without damaging the inner wall; for example, fiber bristles can be used. The outer tube 3 is sleeved around the rotating rod 1, forming a media channel A between them. The outer tube 3 primarily protects the rotating rod 1 and also serves as the wall surface of the media channel A, ensuring that the positive pressure medium can be accurately output from the front outlet B. When the positive pressure medium passes through the media channel A, it will be ejected from the front outlet B, assisting the brush head 2 in cleaning. The positive pressure medium can loosen or blow away the scale that the brush head 2 cannot remove directly, and can also blow the dirt cleaned by the brush head 2 out of the boiler flue 100, thereby improving the cleaning efficiency and cleaning effect of the boiler flue 100.

[0045] The rotating rod 1 is a flexible rod, such as a drain spring, and the outer tube 3 is a flexible sleeve, such as a PVC hose. Even though both are made of hose, they still possess axial force-bearing characteristics, allowing workers to insert the brush head 2 into the boiler flue 100 by holding the outer tube 3. The hose improves the flexibility of the cigarette factory boiler flue cleaning device, enabling it to be flexibly matched to boiler flues 100 of different heights, thus improving cleaning efficiency. Simultaneously, when storing the device, the rotating rod 1 and the outer tube 3 can be coiled, improving the device's structural compactness during storage.

[0046] Once the device is inserted into the boiler flue 100, the rotating rod 1 drives the brush head 2 to rotate along its own axis, beginning the mechanical cleaning of the scale buildup on the inner wall of the flue. Simultaneously, a positive pressure medium is sprayed out from the front outlet B through the medium channel A, assisting the brush head 2 in cleaning and also reducing the temperature of the brush head 2 and the boiler flue 100 during cleaning. Through the combination of mechanical cleaning and medium-assisted cleaning, this device can more effectively remove scale buildup from the boiler flue 100, thereby improving the operating efficiency and safety of the cleaned boiler.

[0047] Since the front outlet B is located at the rear of the brush head 2, the output positive pressure medium can directly impact the brush head 2, thereby efficiently removing the blocky scale entrained on the brush head 2 and avoiding the problem of scratching the inner wall of the boiler.

[0048] Meanwhile, since the medium can flow through the medium channel A when the rotating rod 1 rotates, it can remove the heat generated by the friction between the rotating rod 1 and the outer tube 3, thereby increasing the service life of the rotating rod 1 and the outer tube 3, and thus increasing the overall service life of the cigarette factory boiler flue cleaning device. When the positive pressure medium is liquid, it can also be used to lubricate the rotating rod 1 and the outer tube 3, reducing the rotational resistance of the rotating rod 1 and thus reducing the energy consumption of the cleaning device, further increasing the service life of the cleaning device.

[0049] In summary, the cigarette factory boiler flue cleaning device of this utility model fully combines the advantages of mechanical cleaning and media-assisted cleaning, improving the cleaning efficiency, cleaning effect and service life of the boiler flue 100.

[0050] The cigarette factory boiler flue cleaning device also includes a power assembly 4, which includes a rotating drive and a positive pressure medium generating device. The drive end of the rotating drive is fixedly connected to the rotating rod 1, and the output end of the positive pressure medium generating device is connected to the medium channel A. The power assembly 4 also includes a housing, and the rotating drive and the positive pressure medium generating device are both supported inside the housing.

[0051] In this embodiment, the drive end of the rotary drive component is fixedly connected to the rotating rod 1, and is responsible for providing the power required for the rotation of the rotating rod 1. The rotary drive component can be a motor, capable of continuously and stably outputting rotational power. The output end of the positive pressure medium generating device is connected to the medium channel A, and is responsible for providing a positive pressure medium, such as compressed air. The positive pressure medium generating device can be a compressor, blower, etc., capable of generating and delivering a positive pressure medium as needed. Both the rotary drive component and the positive pressure medium generating device are supported inside the housing, which provides them with protection and support, while also making the device more compact and easier to move.

[0052] During operation, the drive unit of the power assembly 4 provides power, causing the rotating rod 1 to drive the brush head 2 to rotate along its own axis within the boiler flue 100 for mechanical cleaning. Simultaneously, the positive pressure medium generating device generates positive pressure medium, which is sprayed out from the front outlet B through the medium channel A, assisting the brush head 2 in cleaning. This combination of mechanical cleaning and medium-assisted cleaning improves the cleaning efficiency and effectiveness of the boiler flue 100.

[0053] Specifically, the rear end of the outer tube 3 is sealed by a sealing ring to prevent leakage of the positive pressure medium from the rear end of the outer tube 3. The sealing ring can be fixedly connected to the end face of the outer tube 3 and rotates with the rotating rod 1. The surface of the sealing ring that mates with the rotating rod 1 can be a felt surface.

[0054] More specifically, a connecting pipe extends from the rear side wall of the outer tube 3, and the connecting pipe is connected to the output end of the positive pressure medium generating device. Furthermore, the rear end of the outer tube 3 can be fixed to the housing, thus reducing the likelihood of the rotating rod 1 causing the outer tube 3 to rotate due to friction when the rotating rod 1 rotates, thereby improving the reliability of the cleaning device.

[0055] Example 2:

[0056] In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0057] The positive pressure medium generating device includes an air pump, which outputs high-pressure air to the medium channel A. The high-pressure air impacts the inner wall of the boiler flue 100 near the brush head 2, improving the cleaning effect of the boiler flue 100. At the same time, the high-pressure air can remove the heat generated by the friction between the rotating rod 1 and the outer tube 3, thus improving the service life of the rotating rod 1 and the outer tube 3.

[0058] Example 3:

[0059] In addition to possessing all the technical solutions of Embodiment 1 described above, the embodiments of this utility model further possess the following technical solutions:

[0060] The positive pressure medium generating device includes a water pump and a storage tank. The storage tank is connected to the inlet of the water pump, enabling the pump to output cleaning fluid into the medium channel A. The cleaning fluid impacts the inner wall of the boiler flue 100 near the brush head 2, improving the cleaning effect of the boiler flue 100. The cleaning fluid can also remove the heat generated by the friction between the rotating rod 1 and the outer tube 3, extending their service life. Simultaneously, the cleaning fluid lubricates the rotating rod 1 and the outer tube 3, reducing the rotational resistance of the rotating rod 1 and thus lowering the energy consumption of the cleaning device, further extending its service life.

[0061] Example 4:

[0062] Reference Figure 1 , Figure 3 , Figure 5 and Figure 6 In addition to possessing all the technical solutions of any of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0063] The cigarette factory boiler flue cleaning device also includes a plug 5, which is fitted around the outer circumference of the outer tube 3 and can seal the gap between the outer tube 3 and the boiler flue 100 when the brush head 2 is inserted into the boiler flue 100. This prevents the positive pressure medium and impurities on the inner wall of the boiler from leaking out at the rear end of the boiler flue 100, which would affect the operator's grip on the outer tube 3 to carry out flue cleaning work and improve the safety of flue cleaning work.

[0064] Specifically, stopper 5 can be made of rubber.

[0065] Example 5:

[0066] Reference Figure 1 and Figure 3 In addition to possessing all the technical solutions of Embodiment 4 described above, the embodiments of this utility model further possess the following technical solutions:

[0067] The plug 5 is axially slidably connected to the outer tube 3, and the plug 5 can be supported in the boiler flue 100 in a tensioned manner.

[0068] In this embodiment, the plug 5 is fixed in position relative to the boiler flue 100, and the outer tube 3 can move axially along the inner hole of the plug 5. Therefore, the plug 5 will not affect the normal use of the outer tube 3. Since the gap between the plug 5 and the outer tube 3 is small, and the front end of the boiler flue 100 is open, the gap is almost negligible.

[0069] Example 6:

[0070] Reference Figure 5 and Figure 6 In addition to possessing all the technical solutions of Embodiment 4 described above, the embodiments of this utility model further possess the following technical solutions:

[0071] The plug 5 is fixedly connected to the outer tube 3 and is axially slidably connected to the boiler flue 100. A scraping ring 50 is formed on the outer periphery of the plug 5 to abut against the inner wall of the boiler flue 100, so as to scrape off the impurities on the boiler flue 100 when the plug 5 slides axially with the outer tube 3, thereby improving the impurity cleaning effect of the cigarette factory boiler flue cleaning device.

[0072] Specifically, the scraper ring 50 can be set as a rubber ring.

[0073] Example 7:

[0074] Reference Figure 1 , Figure 4 and Figure 5 In addition to possessing all the technical solutions of any one of embodiments 4-6 above, the embodiments of this utility model further possess the following technical solutions:

[0075] The cigarette factory boiler flue cleaning device also includes a mesh bag 6 and a retaining ring 7. The mesh bag 6 is detachably connected to the front end of the boiler flue 100 via the retaining ring 7, and a receiving cavity communicating with the boiler flue 100 is formed inside the mesh bag 6. The retaining ring 7 is detachably connected to the opening of the mesh bag 6, and the retaining ring 7 can be inserted into the boiler flue 100 to press the opening of the mesh bag 6 between the retaining ring 7 and the boiler flue 100.

[0076] During the cleaning process, the rotating rod 1 drives the brush head 2 to rotate within the boiler flue 100, removing accumulated scale and debris. Positive pressure medium is sprayed from the front outlet B, assisting the brush head 2 in cleaning and simultaneously blowing off some debris. The fallen debris is captured by the mesh bag 6 and stored in the collection chamber to prevent it from causing further problems. After cleaning, the mesh bag 6 can be removed from the boiler flue 100 by disassembling the retaining ring 7, and the debris inside can be emptied and cleaned, effectively solving the problem of debris falling during the cleaning process.

[0077] The mesh bag 6 also serves as a filter, with its mesh size designed to allow air and cleaning fluid to pass through while blocking particulate impurities.

[0078] Specifically, when the positive pressure medium is cleaning fluid, a water receiving tray should be installed below the mesh bag 6 to collect the outflowing cleaning fluid.

[0079] Example 8:

[0080] In addition to possessing all the technical solutions of any of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0081] The cigarette factory boiler flue cleaning device also includes a camera, which is fixedly connected to the front end of the outer tube 3. It is suitable for taking pictures of the inner wall of the boiler flue 100 after the outer tube 3 is inserted into the boiler flue 100. The camera can directly take pictures of the inner wall of the flue and capture the scale accumulation, corrosion degree and possible cracks or damage on the inner wall of the flue.

[0082] The camera connects to an external display or recording device to transmit or record images in real time, facilitating observation and analysis by operators. By observing the images, operators can intuitively understand the internal condition of the flue and promptly identify and address potential problems. After cleaning, the camera can also be used to check the cleaning effect, ensuring that the cleanliness of the flue's inner walls meets requirements.

[0083] The flue cleaning device for cigarette factory boilers, by incorporating cameras, not only improves cleaning efficiency but also enables direct detection and recording of the flue's internal condition. This device has significant application value in boiler maintenance and upkeep, ensuring the safe and stable operation of the boiler system, extending its service life, and reducing maintenance costs.
